Answer:
Slope= 2
Y-intercept= -5
Step-by-step explanation:
This inequality is in slope-intercept form which means we can get both striaght from the inequaltiy. Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. In this inequality m would be 2 and b would be -5, so those are your answers.
Misha solves the equation 3 x minus 2 (x + 3) = 4 (x minus 2) minus 7 by applying the distributive property to each side of the equation. The result is 3 x minus 2 x minus 6 = 4 x minus 8 minus 7. Misha then wants to combine like terms. Which are the terms Misha should combine? 3x – 2x and –8 – 7 3x – 2x and 8 – 7 3x – 2x + 4x and –6 – 8 – 7 3x – 2x – 6 and 4x – 8 – 7
Step-by-step explanation:
The given equation is : 3x-2(x+3)=4(x-2)-73x−2(x+3)=4(x−2)−7
On solving this equation and applying the distributive property, we have
⇒3x-2x-6=4x-8-73x−2x−6=4x−8−7
⇒x-6=4x-15x−6=4x−15
Combining the like terms like terms consisting of x are solved together and the constants are solved together,
⇒x-4x=-15+6x−4x=−15+6
⇒-3x=-9−3x=−9
⇒x=3x=3

4 m + 7
Step-by-step explanation:
Simplify the following:
4 (m - 2) + 15
4 (m - 2) = 4 m - 8:

The governor of state A earns $50,145 more than the governor of state B. If the total of their salaries is $295,595, find
the salaries of each.
Answers:
Governor of State A = $172,870
Governor of State B = $122,725
========================================
Work Shown:
A = B+50,145
A+B = 295,595
(B+50,145)+B = 295,595
2B+50,145 = 295,595
2B = 295,595-50,145
2B = 245,450
B = (245,450)/2
B = 122,725 ... salary for governor of state B
A = B+50,145
A = 122,725 + 50,145
A = 172,870 ..... salary for governor of state A
-------------
Check:
A+B = 172,870 + 122,725 = 295,595
So the answers are confirmed.

A model rocket is launched with an initial upward velocity of 156ft/s . The rocket's height h (in feet) after seconds is given by the following. h= 156t-16t^2
The values of t for which the rocket's height is 60 feet are t = 0.40 and t = 9.35
How to determine the values of t for which the rocket's height is 60?The function is given as:
h = 156t - 16t^2
When the height is 60 feet, we have:
156t - 16t^2 = 60
Rewrite as:
16t^2 - 156t + 60 = 0
Divide through the equation by 4
4t^2 - 39t + 15 = 0
Next, we solve the equation using a graphing calculator
From the graphing calculator, we have:
t = 0.40 and t = 9.35
Hence, the values of t for which the rocket's height is 60 feet are t = 0.40 and t = 9.35

Suppose there are two types of tickets to a show: advance and same-day. Advance tickets cost $40 and same-day tickets cost $30. For one performance, there were 65 tickets in all, and the total amount paid for them was $2200. How many tickets of each type were sold?
Advance tickets: represented by x
Same-day tickets: represented by y
you can model this using a system of equations
x + y = 65
40x + 30y = 2200
then you have to get either the x or y value equivalent in both equations
40(x + y = 65)
40x + 40y = 2600
so the new equations are 40x + 40y = 2600 and 40x + 30y = 2200
then you can solve by using elimination
40x + 40y = 2600
-(40x + 30y = 2200)
10y = 400
y = 40
substitute y back into the first equation
x + 40 = 65
x = 25
There are an equal number of pennies, nickels, dimes, and quarters in a bag. What is the probability that the combined value of the four coins randomly selected with replacement will be $.41? express your answer as a fraction in the simplest form.
The probability that the combined value of the four coins randomly selected with replacement will be $.41 is 3/32
In this question, there are an equal number of pennies, nickels, dimes, and quarters in a bag.
We need to find the probability that the combined value of the four coins randomly selected with replacement will be $.41
Out of 41 cents, 1 must be a penny.
And the remaining three (a nickel, dime, and a quarter) must add up to 40 cents.
The first coin must be penny so, its probability P1 = 1
The probability for the second coin would be,
P2 = 3/4
The probability for the third coin would be,
P3 = 2/4
P3 = 1/2
And the probability for the fourth coin would be,
P4 = 1/4
Since the events are independent, the resultant probability would be,
P = P1 × P2 × P3 × P4
P = 1 × 3/4 × 1/2 × 1/4
P = 3/16 × 1/2
P = 3/32
Therefore, the probability that the combined value of the four coins randomly selected with replacement will be $.41 is 3/32

Which figures have rotation symmetry
A form possesses rotational symmetry, often referred to as radial symmetry, when it maintains its appearance following a partial turn rotation. The right answer is D.
Rotational Symmetry: What Is It?A form possesses rotational symmetry, often referred to as radial symmetry, when it maintains its appearance following a partial turn rotation.
The number of alternative orientations in which an object can seem exactly the same for each revolution is the degree of rotational symmetry of that object.
Because of rotational symmetry, the figure should maintain its original appearance even when rotated. So a rhombus is the shape that exhibits rotational symmetry. So, D is the right answer.

To write the given expression 5^3 x √5, as a single power of 5,
First, we will write the expression properly.
[tex]5^{3} \times \sqrt{5}[/tex]
Now, to write the above expression as a single power of 5,
First, express [tex]\sqrt{5}[/tex] in index form
By law of indices [tex]\sqrt{x} = x^{\frac{1}{2} }[/tex]
∴ [tex]\sqrt{5} = 5^{\frac{1}{2} }[/tex]
Now, the expression becomes
[tex]5^{3} \times 5^{\frac{1}{2} }[/tex]
Also, by law of indices, [tex]x^{y} \times x^{z} = x^{y+z}[/tex]

Answer:
The reciprocal we use: [tex]\frac{5}{3}[/tex] ; Answer: [tex]\frac{5}{24}[/tex]
Step-by-step explanation:
The reason why we use this reciprocal is because we are dividing 3/5 from 1/8, so we have to use the reciprocal of the divisor instead. Next, we multiply the numerators and denominators and we get the product of 5/24 and since we cannot simplify further, this is the final answer.

Answer:
1:3:5
20:60:100
Step-by-step explanation:
angles in a triangle add up to 180
so we add 1,3 and 5 to get 9
to find out how much 1 part is worth we do 180÷9 to get 20
so 1 part=20
so we we do:
20x1=20
20x3=60
20x5=100
Answer:
30:60:100
Step-by-step explanation:
angles of triangle =180°
sum of ratios
1+3+5=9
finding for the first one which is one
1/9×180°=20°
finding for the second one which is three
3/9×180°=60°
finding for the third one which is five
5/9×180=100°
adding all the angles
20°+60°+100°=180°
